Bitcoin and Quantum Computing
8 days ago
- Bitcoin's current signature schemes are vulnerable to cryptographically-relevant quantum computers (CRQCs).
- A successful upgrade to post-quantum cryptography requires a soft fork, wallet updates, and user migration, which is complex and uncertain.
- The risk of Bitcoin failing due to a CRQC is the product of the likelihood of a CRQC emerging and the chance Bitcoin fails to upgrade in time.
- Example estimates suggest a 5% chance Bitcoin could be broken by 2030, based on a 10% CRQC likelihood and 50% upgrade failure chance.
- As an investor, this risk represents a floor for valuing Bitcoin at $0, alongside other threats like security breaches or network attacks.
- Users and developers face challenges in choosing PQ signature schemes, managing consensus rules, and motivating ecosystem upgrades.
- The author argues that the risk is significant enough to prioritize PQ upgrades now, despite uncertainties and competing priorities.
- Common counterarguments include dismissing the threat as FUD, noting broader societal impacts, or assuming Bitcoin will adapt without a clear plan.
- The post calls for more technical work, discussion, and community engagement to address the quantum threat proactively.
